My github project at https://github.com/medined/accumulo_stackscript
is designed to install and configure Accumulo on Ubuntu. The project
contains everything except for accumulo itself which is downloaded via
subversion. Looking at the bash script
(https://github.com/medined/accumulo_stackscript/blob/master/linode_build_v00/stackscript)
that drives the whole process might show that you overlooked some
step.
